Hijinks ensued when Pittsburgh Steelers running back DeAngelo Williams posed as an employee at a local Dicks's Sporting Goods and convinced unsuspecting customers to play along with his ridiculous stunts.

The incognito Williams had one customer sit in a kayak while he simulated rough waters, and also asked another wave a Terrible Towel in the middle of the store. The towel-waving fan figured out who Williams was when he was asked to name players on the Steelers offense.

Williams made the day for several fans, even if he did a horrible job wrapping their gifts.
